Adjusted for Five Positions

[CKL1213]

I know this is a dumb request, but can someone post some photos for the Five positions when a watch was adjusted?

Some even said the actual number should be SIX instead of FIVE.

1) Dial up
2) Dial down
3) Crown Right
4) Crown Left
5) Crown Up
6) Crown Down

I tried googled it, but no results on five positions photos.

Any kind soul can enlighten me with photos?

There are also temperature and isochronism considerations..

Aren't 5 enough for you ???

Since it is timed to average those positional variances, I'm not sure that adding another would do much more than waste the watchmakers time..

The tested positions are called 3,6,9 high (meaning that number is uppermost) and dial-up and dial-down..

FYI -my 2008 Datejust / TOG doesn't really respond to any of the suggested positional adjusents. But, YMMV.

The static positions make a small effort at approximating the real-world dynamic conditions that can affect accurate timekeeping.

Pictures may not help you understand as much as a video of a watchmaker actually performing the adjustments.

Actually I'm not trying to understand how it is being adjusted in Five positions.

I'm actually (this is dumb) want to have an idea what is the 5 positions look like.

I was being told the 5 (or 6) positions in words by description was:

1) Dial up
2) Dial down
3) Crown Right
4) Crown Left
5) Crown Up
6) Crown Down

I'm sure those who have a Timegrapher machine can measure up to 5 positions.

So I would like to know how it look like in that 5 positions.

Your kindness for taking up the photos will be very much appreciated

My Timegrapher also has 45 degree positions with give a lot of combinations.
I gave up at 14?
I had a busy day.

Pictures like these?


Dial Up



Crown Right



Crown Up



The other postions look a lot like these and the post with a good description of what a novice regulator did with his timegrapher is worth a quick read.

And the timegrapher website has more pics like those: http://www.timegrapher.com/tymc/mtg_500.html

No photos, but what COSC does is test Dial Up, Dial Down, 3 o'clock up, 6 o'clock up and 9 o'clock up. Those are the 5 COSC positions.

12 o'clock up is actually not tested (the missing position out of the full possible 6 ways), because it is felt that watches are almost never in that position (unless you want to put it in front of your nose to check the dial). Now some say that "truck drivers wear it on the inside of the wrist so they need that position included) and I for one agree (but not the truck driver part!).

The main rationale that COSC eliminates the 12 o'clock up position is that with all the Swiss manufacturers testing over a million units a year at 2 different temps, this save 2 days of COSC testing per unit which ultimately is a lot of reduced workload, and they feel watches just don't run that way very much.

Interstingly, Grand Seikos are in fact tested in all 6 possible positions in order to gain GS Certification, but they turn out a few thousand a year, at most, so the saved workload is not as big of a deal.

Old thread, I know, but very much on point for my question.



Can anyone tell me what my Rolex 710 (chronometer) movement was subjected to if it says "Adjusted to 7 seven positions"? Pic attached.

I met a watchmaker who works at a Rolex certified jewelery here in Ottawa, Canada. He confirmed that in the early 40s Rolex put out a few movements that were ajusted at the 5 COSC positions plus 12 o'clock up (a 6th position rarely tested) plus a unique seventh position that is crown at 45 degrees angle with ground. Imagine making a military salute... This would make the "adjusted to" portion of the statement true. A true waste of a watchmaker's time, but a rarity nevertheless...
